UNITED STATES PATENT OFFICE EPPA H. RYON, OF WALTHAM, MASSACHUSETTS,ASSIGNOR OF ONE-HALF TO A. M. GOODALE, OF SAME PLACE.

SPINDLE AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 616,020, dated December13, 1898.

Application filed February 20,1897. Serial No. 624,392. (No model.)

To all whom it may concern:

Be it known that I, EPPA H. RYON, of VValtham, county of Middlesex,State of Massachusetts, have invented an Improvement in Spindles andSupports, of which the following description, in connection with theaccompanying drawings, is a specification, like letters and figures onthe drawings representing like parts.

In this invention I employ a spindle provided above and below the whirlwith inclinedsurfaces which run against a series of balls or rollingsurfaces surrounding the spindle, such construction enabling me todispense with the use of a bolster for the reception of the pintle ofthe spindle, my improved spindle not requiring any oiling.

Figurel in partial vertical section shows a spindle and its supportembodying my invention; Fig. 2, a top or plan View of the spindle shownin Fig. 1; Fig. 3, a section below the dotted line 00, Fig. 1.

' The spindle-rail A receives upon it a supporting-case B, it beingconfined in place by a suitable nut B. This supporting-case is shown asentirely open at its lower end and as cut out at one side for thepassage of the usual driving-band about the whirl C of the spindle C. Iv

The pintle a of the spindle is extended loosely through a hole in a cupa, surrounded by a packing a and then through the open shank of thesupporting-case, as shown, and above the said cup the spindle has fixedto it a tapered surface I), then a whirl O, and a' second taperedsurface I), and a threaded sleeve 6 the said sleeve having screwed uponit the conical seat d, which enters or contacts with the lower end ofthe usual bobbin, (not shown,) which will be carried by the blade of thespindle. v

The inclined surface I) rests on a series of balls or rolling surfaces(2 in the cup, while the tapering surface I) supports a series of ballsor rolling surfaces 6, acted upon by a flange of a ring a", screwed intothe upper end of the supporting-case, said ring having a series ofnotches 2, one of which is entered by a locking-pin 6 These taperingsurfaces, made as collars, are suitably connected with the spindle, soas to project outwardly therefrom above and below the band-groove of thewhirl. They may be shrunk onto the spindle or be secured in place in anysuitable manner.

The cup may have a slight lateral play or slip due to the packing to soprevent any jar ring in running.

It will be noticed that the set of balls 8, supported by the taperingsurfaces Z2, occupying a position wholly above the upper edge of theband-groove of the whirl, have a constant tendency to sink or roll downthe said tapered surface against the inner wall of the flanged ring, andconsequently the said wall always presents a rolling surface between thesaid tapering surface fixed to the spindle and the outer surroundingstationary ring, and so, also, the set of balls e, sustaining the weightof the spindle, are acted upon by the tapering surface b, connected withthe spindle at a point entirely below the lower edge of the band-grooveof the whirl, and said taperingsurface, notwithstanding any wear betweenit and the balls, will always by gravity keep firm contact with theballs and will force them outwardly against the'fiange of the cup a.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A supporting-case, acup therein, a packing interposed between saidcup and said case, a series of balls e located in said cup, combinedwith a spindle having a whirl, and an inclined surface locatedthereon'and projected therefrom below the under side edges of theband-groove of said whirl, and extended from said whirl downwardlytoward the surface of the spindle and running on said balls,substantially as described.

2. A supporting case, and a spindle carrying a whirl and provided withtwo inclined surfaces, the larger diameter of one of said inclinedsurfaces extending from the lower edge of the band-groove of the whirldownwardly and inwardly toward the spindle, the

other of said inclined surfaces extending up wardly and inwardly fromthe upper edge of the bandgroove of said whirl toward the spindle;combined with a flanged cup supporting said spindle and located withinthe lower portion of said supporting-case, and a flanged ring adjustablymounted in the up- In testimony whereof I have signed my per end of saidsupporting-case, and two sets name to this specification in the presenceof 10 of rolls, one set occupying a position between two subscribingwitnesses. one of said tapering surfaces and said flanged 1 T T 5 cup,while the other set occupies a position be- BPPA R1 tween the other ofsaid tapering surfaces and \Vitnesses:
